It is respectively equipped with the first lifting external member and the second lifting external member between first vertical plate and second vertical plate, described the
Structure phase is respectively equipped between one vertical plate and the first lifting external member, between second vertical plate and the second lifting external member
Same the first linkage mechanism and the second linkage mechanism, the linkage mechanism include movable pulley and are wound around mentioning on the movable pulley
Drawstring, the both ends of the rope are separately fixed on corresponding vertical plate and corresponding lifting external member；It is hung on two movable pulleys
There is pull rod, the two pull rod lower ends are respectively connected with safety tongs.
Further, it is equipped with speed limit external member in the middle part of the connecting rod, the speed limit external member is fixedly connected and leads to the connecting rod
It crosses limiter of speed connecting plate and is connected to the limiter of speed；
When elevator overspeed is run, the limiter of speed triggers the speed limit external member by the limiter of speed connecting plate and rotates.
Further, the linkage mechanism further includes position-limited box, and vertically extending fluctuating orbit is equipped in the position-limited box,
The movable pulley can be moved along the fluctuating orbit.
Further, the position-limited box two sides offer the kidney slot being pierced by for the rope.
The utility model, by triggering link rotatable, drives lifting external member rotation in elevator overspeed, and lifting safety tongs makes
Its seized guide rail, while original pull rod stretching structure is replaced with into movable pulley stretching structure, enhance the system of safety tongs
Power, further ensure elevator using safe.
